My small press pot actually makes around 12 us fluid ounces of coffee at the strength I like, with a fairly thick filter bed. Almost identical shape and dimensions as an aeropress, so it works interchangeably in that regard.
I agree, would be great to get a glass aeropress cylinder - though what makes me most hesitant to use one is actually the plunger/seal. I had one that I bought about 10 years back that sat for a couple months without use and it got very tacky and sticky, and it was very difficult to clean off. I'm not sure what that material was, but the fact that it isn't there when I used it regularly told me that whatever it was, it was going into my cup. Now when I use (my new aeropress), I wash the plunger first and I don't brew inverted - ensuring that my beverage doesn't come in direct contact with the rubber part.
I've had the sticky plunger happen to me when my work aeropress was sat unused for a few months. I thought it was the sunshine/UV degrading the rubber and didn't really think about whether it puts contaminants into the coffee - I just bought a replacement rubber bung for it (they do wear out over a few years usage as well).
Edit: Just looked it up and the plunger is made out of thermoplastic elastomer (food grade)
Edit2: Found a discussion about a glass aeropress and there would be a couple of drawbacks. Firstly, the glass would likely need to be pre-warmed due to the increased heat capacity. Secondly and more importantly, glass wouldn't be strong enough to survive daily usage and I know I've certainly dropped my aeropress onto the floor enough times to know that indestructible plastic is definitely better for me.
